Supports filter lists compatible with Adblock Plus syntax and hosts files, but is a lot more efficient than its rivals and offers more advanced functionality.

After using ublock it is easy to notice how other similar addons slow Firefox down, ublock is slimmer in memory usage and uses less CPU time due to a more efficient design. uBlock actually makes your browser leaner unlike many similar addons.

This version (uBlock Origin) is developed by the original uBlock add-on author (the creator of uBlock) and has a more advanced feature-set than uBlock, but doesnt support legacy Firefox versions.

A lot faster than most alternativesRated 5 out of 5 stars

I have tested this on many different computers and configurations and on every single one I can immediately see the improvement in performance compared to e.g. Adblock Plus, regardless of how powerful the system is.

µBlock is blazing fast even with 160 000 filters compared to ABP with 89 000 filters, a lot less jank and jamming, faster startup... Its amazing. Not to mention the improved blocking power, ability to block and examine behind-the-scene requests, the local caching feature if we get it back...

The only drawback is that the UI is less powerful and less informative in certain ways and there is no built-in subscription issue reporter. But I can live with the certain UI drawbacks, since the performance, blocking power improvements and other features make up for it tenfold.

The authors are also proactive and eager to improve the addon and I like their honesty. Cant wait to see this addon mature further.

What is "updated"?Rated 1 out of 5 stars

What is updated? Is this similar to https://addons.mozilla.org/en-US/firefox/addon/inlinedisposition-reloaded/ so that it also changes "file" to "attachment"? Or does this fix the longstanding bug outlined here https://addons.mozilla.org/en-US/firefox/addon/inlinedisposition/reviews/522904/ ? Or what?

Why would I install this since you dont give any info why have you forked the original? Added something nefarious?

Will update review when I get more info.

Edit: Thanks that looks interesting, but I still dont know what makes this different from the other 2 similar add-ons here. Why would I want to install this instead of the original or "reloaded" that also changes file to inline? What is updated?

"What the add-on's description doesn't say is that since version 1.3 (released on April 19th 2012) it has also sent - unencrypted - the full URL of sites visited using HTTPS, and sites viewed in Private Browsing mode, to a site called ip2info.org.

The user never realises that the data has been shared with a third-party, unless they use special tools to monitor what data is being sent from their computer.

SophosLabs researcher Xiaochuan Zhang examined the add-on, and observed the potential privacy breach in action. In the following example, he used Wireshark to view the network packets being sent and observed his request to visit a non-existent website "www.thisisapparentlyafakeservice.me" being shared with ip2info.org.

The full URL of every webpage visited is sent to the Germany-based ip2info.org website, using unencrypted connections.

In addition, the add-on has no warning that sites you visit might be disclosed, no privacy policy small print explaining its behaviour, and no apparent way to opt-out of the data-sharing."

Does it's job but still has a few "flaw"s worth mention:- Please add better PNG compression, currently it's not very efficient- I wonder why the 'Annotate Your Screenshot' -page, that shows up after taking a screenshot of a webpage showing you the screenshot and letting you edit it, has content over the internet such as 'http://readict.com/promotion/ff/script-for-AW.js' and 'https://ssl.google-analytics.com/ga.js'
